This dishwasher lets you do dishes at the speed of life so you can conquer your daily chores in less time. LG’s innovative QuadWash Pro and Dynamic Heat Dry technologies combine to deliver maximum cleaning coverage and thorough drying performance for clean and dry dishes, faster than ever before. That means you can spend less time waiting on dishes and more time on what matters. Plus, our TrueSteam technology helps to penetrate food residue, reduce water spots and sanitize your dishes.
1-Hour Wash and Dry
LG's exclusive QuadWash Pro and Dynamic Heat Dry technologies combine to deliver a 1-hour wash and dry cycle¹ for sparkling, table-ready dishes in less time. So you can spend more time on what matters.
Dynamic Heat Dry
Our Dynamic Heat Dry technology circulates hot air throughout the dishwasher for faster, more complete drying², delivering sparkling, table-ready dishes right off the rack.
QuadWash Pro
High-pressure jets with 38% more cleaning power³, spray dishes from multiple angles while soaking them with over one million microbubbles to help break down stubborn food residue.
ThinQ Care
Keep your appliances running smoothly with ThinQ Care, now in the ThinQ app. Get notifications about usage, maintenance, plus early diagnosis right on your phone. ThinQ Care will help you understand your appliance needs, avoid potential problems, and keep your appliance running its best.
TrueSteam with Sanitization
LG TrueSteam uses steam to penetrate food residue and help eliminate water spots up to 60%⁴. LG dishwashers are National Sanitization Foundation certified and reach a final rinse temperature greater than 150°F when operated on the Steam cycle⁵.
EasyRack Plus
The EasyRack Plus system provides outstanding flexibility and convenience. It adjusts to just about any load of dishes to help ensure optimal cleaning. Easy to adjust on the fly, you can change the upper rack height to three different levels with one touch.
LED Tub Light
Now you can check on dishes in an instant with the help of interior LED lighting. Two integrated tub lights turn on when the dishwasher door is opened, so you can easily check on your favorite mug.
Remote Start
Conveniently start your dishwasher remotely with the ThinQ app, so no matter where you are, your dishes will be ready when you need them.
ThinQ Technology
LG's ThinQ app helps you manage your LG Smart appliance and more to make your day a little easier and keep your home running smarter. Compatible with Alexa and Google Assistant and available for iOS and Android platforms, this free app will help you run your home like a pro.
Glide Rail and Ball-bearing Wheel Design
Your heaviest dish loads glide in and out smoothly with the help of LG's Glide Rail and Ball Bearing Wheel design. The Glide Rail keeps the upper rack on track while the ball-bearing wheel provides a smooth lower rack glide for easy loading and unloading.
Why waste time fighting a dishwasher rack that goes off track, especially when you’re in a hurry? The lower rack’s ball-bearing wheel design rolls out effortlessly—even when loaded with heavy pots and pans.
Flex Zone
Flex Zone lets you customize your cleaning to target different zones inside the dishwasher, including upper or lower rack only, and adjust wash intensity as needed for each zone.
Auto Cycle
With LG Auto Cycle you have one less thing to think about. This feature automatically senses the level of dirt on your dishes and sets the wash cycle, so your dishes get optimal cleaning every time.
LoDecibel Operation (42 dB)
LG's technological advances, like the Inverter DirectDrive motor and the advanced 3-stage filtration system, were designed with quiet in mind. At 42dB, this dishwasher is among the quietest dishwashers in its class.
15 Place-Setting Capacity
The spacious, stainless steel interior provides ample space for lots of dishes and stemware, in a variety of sizes. Fit up to 15 place-settings of dishes.
Top Control Panel With LED Display
Top controls with LED display are easy to see and use when the dishwasher door is open but hidden from view when the door is closed, for a seamless look that’s also easy to clean.
PrintProof Finish
Now you can have all of the things you love about stainless, without the need for special cleaners or constant attention. LG’s PrintProof fingerprint and smudge resistant finish easily wipes clean with a soft, dry cloth for a distinctive kitchen that handles real-life in style.
3-Stage Filter System
LG's advanced filtration system is tough on food residue and dirty dishes even if you don't pre-wash. Plus its advanced design makes it extremely efficient and quiet.

Q: QuestionIs this unit supposed to ship with the sound insulation? They forgot it and it’s LOUD.(5 answers)
A: AnswerThere should be a thick sound insulation blanket over the top and sides of the washer, our washer is unbelievably QUIET-much more quiet than dishwasher we’ve ever owned, including Bosch and Kitchen Aid.Answered by JohnB
Q: QuestionWhat are the packaged dimensions? Like before it’s taken out of the box.(1 answer)
A: AnswerHello there! Thank you for your inquiry. We're happy to provide you with the packaging or carton dimensions of the LG LDTH7972S. The dimensions are 28" x 34 3/4" x 29 5/8" (in) for width, height, and depth respectively. Additionally, the shipping weight of the product is 109.13 lbs. We hope this information is helpful to you! - ShaeAnswered by LG Digital Customer Care
- A: AnswerThe green light will light after cycle is complete. The red light will light if there is some sort of error in addition to an error code being displayed where the cycle time would normally be displayed. As far as the other light I dont know since I have never seen that one.
Answered by Robert
Q: QuestionDoes this model LDTH7972S have the auto open feature(3 answers)
A: AnswerNo, but it does have a "night dry" function which circulates air if the dishwasher will remain closed for hours after cycle completion. Dishes and plastics come out dry and fresh.Answered by JohnB
- A: AnswerHello there. Thank you for your interest in the LG LDTH7972S Top Control Dishwasher. We understand you’d like to match it with your kitchen’s aesthetic. This model does not support custom door panels, such as wood, as it’s designed with a fixed stainless steel front. Modifying the panel could affect the door’s functionality and void the warranty. https://www.lg.com/us/dishwashers/lg-ldth7972s-top-control-dishwasher#pdp_specs If you need more details or assistance, please send us a private message on Social Media @LGUSSupport. We’re here to help! —Renzo
Answered by LG Digital Customer Care
- A: AnswerYeah, it looks like Best Buy has the wrong warranty information listed. People are purchasing this dishwasher expecting a 5 year warranty on the control board and rack parts, but they are actually only receiving 2 years per LG's own site (see attached images). Buyer beware I guess...
Answered by LarryP
Q: QuestionDoes this dishwasher fully dry dishes after the cycle?(1 answer)
A: AnswerHi there, Metalpro. Thank you for your question about the LDTH7972S Dishwasher! We understand that a fully dried load is important after the cycle. This model features Dynamic Heat Dry™ and Hybrid Condensing Drying System, which work together to effectively dry your dishes after the wash cycle. Additionally, it has a Heated Dry option and Dry Boost for even better drying performance. For optimal drying results, we recommend ensuring that the Rinse-Aid dispenser is filled, as this can help improve the drying process. https://www.lg.com/us/dishwashers/lg-ldth7972s-top-control-dishwasher#pdp_specs If you have any further questions or would like more information, feel free to send us a private message on social media @LGUSSupport, and we’ll be happy to assist you! —RenzoAnswered by LG Digital Customer Care
- A: AnswerThere are two buttons on each side of the rack Push them in and push rack in. Hope that helps! Call LG

Great dishwasher with lots of functionality
My wife and I never really used dishwashers. We moved into a new place that had a fairly new dishwasher and it didn't change our opinion at all. After debating it for a long time we decided on this model. My wife and I now use a dishwasher every few days. I really like the steam function on this LG, though I was advised by the installer to be careful on opening the dishwasher mid wash (careful for kids). You can opt out of a steam wash. I also like the LG app that lets you monitor the status of your wash. I like to empty dishwasher as soon as I get the alert it is complete with the wash. I also enjoy the light inside and the top pull out drawer for utensils. It is also very quiet and sometimes I can't even hear it when its on and I am 15 feet away.

Love this dishwasher
Wasn’t sure what we were looking for went to two other stores first they all had us waiting 2 to 3 weeks. Not sure even what to buy got here had so many people helping us out even the manager came which was not the first time in the last couple months. After a few choices decided on this one and couldn’t be happier so quite (much quieter than my Bosh) and the dishes come out unbelievably clean.

Fantastic dishwasher
This is the quietest dispatcher I've ever owned and the dishes come out very clean. The only questionable performance area is the third tray at the very top. I love that there is a light that turns on when you open the door like a refrigerator.
